Fixed, on main.
The fix will only work in Emacs 30+, because it requires Emacs bug fix
described in https://debbugs.gnu.org/cgi/bugreport.cgi?bug=70671
https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=e36a4fe20

Confirmed.
This is because `org-html-final-function' uses `mhtml-mode' to indent the
resulting html file. `mhtml-mode' unconditionally runs `prog-mode-hook'
thus starting Ispell.

We may try `delay-mode-hooks' around `set-auto-mode', but it is not
honoured by `mhtml-mode'. I guess we can report this as Emacs bug.

This sounds like a normal Ispell behaviour.

TIL!  Thank you.

I apologize for not providing a sequence of reproduction steps.

Upon further investigation, Org frequently starts and kills the
spellchecker when the document contains `LocalWords' comments.

1. Start Emacs

   emacs -Q

2. Configure Flyspell

   (add-hook 'text-mode-hook #'flyspell-mode)
   (add-hook 'prog-mode-hook #'flyspell-prog-mode)

3. Create a new Org file

   # LocalWords: xyz
   
   Hello there!

4. Export the file to HTML

Expected:

  No Ispell process started on export.

Actual:

  A new Ispell process started on export.

P.S. I also see Org starting Ispell over and over when holding down
`C-v' in a long document that contains lots of scattered `LocalWords'
comments.

Note how I change the email subject to mark a new topic.
In Emacs, it is M-x message-change-subject

I am unable to reproduce using the latest Org.
